When is veterinary internal medicine necessary?

Veterinary internal medicine deals with complex or chronic diseases that require a global view and continuous follow-up of the patient.

Symptoms requiring internal medicine assessment

When symptoms are persistent, varied or non-specific, internal medicine allows for a comprehensive investigation of the cause.

  • Weight loss or appetite

  • Recurrent vomiting or diarrhoea

  • Changes in behaviour or general condition

Diagnosis and control of internal diseases

Many internal pathologies require accurate diagnosis and long-term follow-up.

  • Kidney, liver or endocrine diseases

  • Chronic digestive disorders

  • Metabolic or immunological disorders

Monitoring and coordination between specialities

Internal medicine acts as a central hub for coordinating diagnostic tests and other veterinary specialties.

  • Integration of analysis and diagnostic imaging

  • Adjustment of treatments according to evolution

  • Collaboration with cardiology, dermatology or other areas

What information helps in diagnosing an internal illness?

Some internal illnesses produce non-specific symptoms, appear intermittently or develop slowly. Keeping a record of what happens at home can help the veterinary team piece together the progression of the problem and select the most appropriate tests.

Before your appointment with the consultant in internal medicine, please try to gather the following information.

Make a note of when the symptoms started

Draw up a simple timeline that includes:

  • When did you first notice the change?

  • Whether the symptoms are ongoing or occur in episodes.

  • How often do they occur?

  • How long is each episode?

  • If they have become more intense.

  • If they seem to be related to food, exercise, rest or medication.

  • What treatments have been used and how did the pet respond?

You don’t need to remember every detail exactly. A structured approach may be more helpful than simply describing your symptoms from memory during the consultation.

Observe their usual routines

Changes in your daily routine can provide important information. In the days leading up to your appointment, pay attention to:

  • Appetite: whether they eat less, more or at irregular intervals.

  • Water consumption: if they drink more frequently or empty the container sooner.

  • Urine: amount, frequency, colour and any difficulties.

  • Statements: consistency, frequency, presence of mucus or blood.

  • Weight: a loss or gain for no apparent reason.

  • Activity: fatigue, a reduced interest in playing, or difficulty carrying out everyday activities.

  • Breathing: coughing, faster breathing or reduced exercise tolerance.

  • Behaviour: withdrawal, irritability, restlessness or changes in sleep patterns.

Persistent changes in appetite, weight, thirst, urination or activity levels may warrant a veterinary assessment, particularly when several of these occur at the same time.

Record the episodes whenever possible

A video can be useful if the symptom does not occur during the consultation. You could record, for example:

  • Bouts of coughing.

  • Retching or the urge to vomit.

  • Difficulty breathing.

  • Tremors or weakness.

  • Gait abnormalities.

  • Changes in behaviour.

  • Brief episodes of disorientation.

Photographs can also help to show any changes in your pet’s stools, urine, abdomen, skin or mucous membranes. Do not delay making an appointment just to take a photo if your pet’s condition worsens.

Please bring a list of your medicines and diet

Make a note of all the products your dog or cat receives:

  • Prescription and over-the-counter medicines.

  • Dosage and timing.

  • Supplements and dietary supplements.

  • Antiparasitic agents.

  • Pet food, wet food or a home-cooked diet.

  • Prizes and leftovers.

  • Recent changes to their diet.

Do not stop, combine or alter a course of treatment without veterinary advice. Do not change your pet’s diet before the appointment unless the team has recommended it.

When diet can influence the condition or form part of the treatment, we coordinate the case with the veterinary nutrition.

Compile the previous reports and evidence

If your pet has been treated at another clinic, please bring all the available documentation with you:

  • Veterinary reports.

  • Laboratory results.

  • X-rays, ultrasound scans or CT scans.

  • Hospitalisation reports.

  • Previous diagnoses.

  • Treatments and the response achieved.

  • Approximate dates of relapses or changes.

Monitoring how results change over time can be just as important as interpreting a single test.

Vets who need to refer a patient for a specialist assessment can use the service provided by Case studies from Benivet Benissa.

What tests might be recommended?

Not all patients require the same tests. The choice of tests depends on the symptoms, the physical examination, the patient’s medical history and previous test results.

The study may include:

Tests are recommended on a step-by-step basis and only when they can provide relevant information to guide the diagnosis or monitor the patient’s progress.

When might hospital admission be necessary?

Some patients require intravenous medication, fluid therapy, repeated checks or closer monitoring. In these situations, treatment may continue in the veterinary hospitalisation.

Please contact the clinic as soon as possible if your pet shows signs of a sudden deterioration, difficulty breathing, severe weakness, repeated vomiting, an inability to urinate, loss of consciousness or a noticeable deterioration in their general condition.

Does your dog or cat have recurring symptoms, abnormal test results or a condition that requires monitoring? Book an appointment for veterinary internal medicine or call +34 622 325 271.

Estamos muy agradecidos con el equipo de Benivet Benissa por la atención y el cuidado que han tenido con nuestro perro. Llegamos a la clínica después de varias semanas de problemas en la piel y de haber probado diferentes tratamientos sin conseguir una mejoría real. Nuestro Yorkshire, que ya tiene 14 años, tenía heridas, zonas muy inflamadas y pérdida de pelo. En Benivet realizaron las pruebas necesarias y finalmente encontraron la causa: una demodicosis grave con una infección bacteriana secundaria. Nos explicaron todo con mucha claridad y empezamos un tratamiento específico. Aunque el tratamiento todavía no ha terminado, la mejoría ha sido enorme: las heridas han desaparecido, la piel está mucho mejor, las zonas oscuras de las patas están desapareciendo y el pelo ya está empezando a crecer de nuevo. En la última revisión todavía quedaban algunas bacterias, por lo que nos han prolongado el tratamiento una semana más. Queremos agradecer especialmente la profesionalidad, la atención y la paciencia que han tenido con nosotros y con nuestro pequeño. Después de todo lo que habíamos pasado, por fin sentimos que nuestro perro está en buenas manos. ❤️ Muchas gracias a todo el equipo de Benivet Benissa. 🐶❤️

Durante los últimos dos meses hemos vivido momentos muy difíciles y llenos de incertidumbre. Nuestro galgo macho de 5 años se rompió una pata y además tenía un tumor. Para resumir una historia bastante larga: afortunadamente resultó no ser cáncer, pero finalmente tuvieron que amputarle la pata y ha pasado por momentos de mucho dolor. Estamos enormemente impresionados y agradecidos con todo el personal de esta clínica. Tanto el equipo de veterinarios como el personal de apoyo se comunican perfectamente, son muy empáticos y atentos, pero al mismo tiempo proactivos y tremendamente profesionales. Sinceramente, no tenemos ni un solo punto de crítica. Estamos simplemente muy felices de haber llegado a esta clínica y, sin ninguna duda, a partir de ahora serán nuestros veterinarios de confianza. **Gracias por todo, querido equipo de la Clínica Veterinaria Benivet.** ❤️ Willem y Javi

Fuimos el viernes por la tarde porque nuestro gato se comió un hilo largo. Las veterinarias fueron súper pacientes a pesar de que el gato se puso peleón por el miedo. Le hicieron ecografía y luego lo metieron a cirugía casi inmediatamente. El cirujano fue excelente, nos explicó todo el procedimiento y nos avisó por WhatsApp cuando estuvo listo el gatito, se quedó en observación y al día siguiente lo hemos recogido. La operación fue impecable y el gatito está en casa, la sutura está perfecta. Fueron excepcionales.

Lleve a mi gato de 6 años de urgencia porque se había tragado un hilo largo y gordito, y por la mañana vomitó un trozo. Menos mal que lo hice ya que al día siguiente era festivo, y haber esperado más habría resultado seguramente en necrosis y perforaciones intestinales. Mi gatito fue muy bien atendido por todos los veterinarios. Lo sedaron porque estaba nervioso, le hicieron ecografía para encontrar el hilo en el yeyuno, ya medio plegado, y lo operaron. Fue caro pero lo pagaría de nuevo, porque la vida de mi gatito no tiene precio y lo atendieron aún cuando iban a empezar después de su hora de cierre. Además está mañana al recogerlo estaba bien, tranquilo y dolorido, y la sutura se ve super limpia y bien hecha. Mis agradecimientos a Constantino y al resto de veterinarias que atendieron a mi gato.

No tenemos más que agradecimiento para todo el equipo de Benivet Benissa. Llevamos a nuestro perro Dachs para una cirugía de columna delicada —una hernia que le comprimía la médula— y desde el primer minuto nos transmitieron una tranquilidad enorme. Incluso nos avisaron de la dirección exacta para no confundirnos con otra clínica que hay a pocos metros: un detalle pequeño que ya dice mucho de cómo trabajan. Queremos destacar especialmente a dos personas. Al traumólogo, Constantino, que hizo un trabajo impecable: retiró toda la hernia y liberó la médula sin complicaciones. Y a la anestesista, Ana, que cuidó cada detalle —algo nada menor en una intervención así—. Gracias a ambos, en las primeras 24 horas Dachs ya recuperaba movilidad voluntaria en la pata. Cuando surgió un pequeño imprevisto con la sonda, lo resolvieron al momento y con total profesionalidad. Pero si algo destaca por encima de lo médico es el trato humano de todo el equipo. Nos mantuvieron informados con mensajes constantes y cercanos, nos escribían para contarnos que Dachs "se portaba muy bien", que nos deseaba buenas noches, e incluso se adelantaron ofreciéndonos un arnés de apoyo por si lo necesitaba. Se nota que aquí no solo tratan a los animales: los cuidan de verdad. Gracias de corazón a Constantino, a Ana y a todo el equipo de Benivet.

When internal medicine is indicated and what tests/services can complement it

The veterinary internal medicine is indicated when there are symptoms that require a global approach (digestive, respiratory, urinary, endocrine, weight loss, malaise, recurrent fever) or when a disease requires monitoring and adjustments in the medium/long term. At Benivet Benissa we start with a clinical history and complete examination and, if the cause needs to be confirmed or the evolution needs to be controlled, we indicate tests only when they provide useful information:

Veterinary practice in BenissaInitial assessment, complete examination and definition of the diagnostic plan.

Blood tests y urinalysisBasis for assessment of general condition, inflammation, liver/kidney function, metabolic disturbances and treatment management.

Coprological tests / stool analysisif there is persistent/recurrent diarrhoea, mucus/blood in stool or suspicion of digestive parasites/infection.

Veterinary ultrasoundvery useful in abdominal problems (repeated vomiting, pain, weight loss) and to assess organs and soft tissues.

Veterinary radiologySupport for chest (cough/breathing difficulties), abdomen and some emergencies or chronic processes.

Microscopy and cytologywhen we need to study cells/inflammation/infection (skin, ears, lumps or some internal processes as the case may be).

If the patient requires close control or ongoing treatment (fluid therapy, medication, monitoring), we can rely on veterinary hospitalisation. And if there are co-morbidities that affect the plan (e.g. chronic pain or overweight), we coordinate it with PAIN UNIT y veterinary nutrition.

👉 If your pet has recurrent symptoms or you need to monitor a chronic disease, request an appointment here or call +34 622 325 271.

Where we are

Frequently asked questions about our veterinary internal medicine service

The veterinary internal medicine is concerned with the diagnosis and treatment of diseases affecting internal organs and systems such as digestive, respiratory, urinary, endocrine, immunological, haematological, haematological and other complex processes. This includes, for example, chronic vomiting and diarrhoea, weight loss, liver or kidney disease, diabetes, anaemia, autoimmune diseases or systemic infections.

It is advisable to consult internal medicine when your pet presents with persistent or recurrent symptomssuch as vomiting or diarrhoea lasting several weeks, chronic cough, respiratory distress, unexplained weight loss, increased thirst and urination, episodes of fever, prolonged listlessness or abnormal results in previous blood tests. Also when other treatments have not had the expected response.

Depending on the case, this may include:

  • Blood and urine tests complete

  • Hormone tests and specific profiles

  • Abdominal ultrasound and X-rays

  • Cytology, biopsy or advanced laboratory tests

  • Rapid tests for infectious diseases

The aim is to obtain a patient overview and arrive at an accurate diagnosis before treatment is considered.

In many cases, yes, but in internal medicine, there are diseases multifactorial or highly complex in which the diagnosis may be of high probability rather than 100 definitive %. Even so, with a good combination of clinical history, examination, imaging and laboratory tests, it is often possible to narrowing down the most likely causes and establish an effective management plan.

It depends on the disease. Some pathologies are completely resolve after a specific treatment (infections, acute processes), while others, such as certain renal, endocrine or immune-mediated diseases, require chronic management and regular reviews. At Benivet Benissa we explain the prognosis and the type of follow-up expected in each case.

Your role is crucial. Many internal medicine diseases require:

  • Administering medication at specific times

  • Controlling the diet and access to water

  • Observe and note changes in appetite, weight, behaviour or symptoms.

  • Attending the reviews and control analyses

The joint work between tutor and veterinary team is key to achieve the best result in the medium and long term.
